This is an article that most other website developers probably don’t want you to read. The reason is that most other web designers basically like to think of themselves as all-powerful wizards with magical powers. And they use complex technical jargon and terminology to intimidate and mystify their clients into thinking that what they do is more complex than it is.
I know there may have been concerns that the ADA may be too vague or too costly, or may lead endlessly to litigation. But I want to reassure you right now that my administration and the United States Congress have carefully crafted this Act. We've all been determined to ensure that it gives flexibility, particularly in terms of the timetable of implementation; and we've been committed to containing the costs that may be incurred.... Let the shameful wall of exclusion finally come tumbling down.[41]

Signed in 1990 at a time that most people hadn’t even used the Internet, the Americans with Disabilities Act does not explicitly regulate how websites need to follow nondiscrimination requirements. We now know that using the Internet is one of the most important ways for people with disabilities to fulfill their needs and desires. For many people with disabilities, especially impairments to sight and motion, visiting a store or other physical location can be a challenging experience. Online shopping, for example, allows people with disabilities to make the purchases they need easily and securely within the comfort of their own homes.

The ADA has been criticized on the grounds that it decreases the employment rate for people with disabilities[48] and raises the cost of doing business for employers, in large part due to the additional legal risks, which employers avoid by quietly avoiding hiring people with disabilities. Some researchers believe that the law has been ineffectual.[49] Between 1991 (after the enactment of the ADA) and 1995, the employment rate of men with disabilities dropped by 7.8% regardless of age, educational level, or type of disability, with the most affected being young, less-educated and mentally disabled men.[50] Despite the many criticisms, a causal link between the ADA and declining disabled employment over much of the 1990s has not been definitively identified.[51]

Many members of the business community opposed the Americans with Disabilities Act. Testifying before Congress, Greyhound Bus Lines stated that the act had the potential to "deprive millions of people of affordable intercity public transportation and thousands of rural communities of their only link to the outside world." The US Chamber of Commerce argued that the costs of the ADA would be "enormous" and have "a disastrous impact on many small businesses struggling to survive."[35] The National Federation of Independent Businesses, an organization that lobbies for small businesses, called the ADA "a disaster for small business."[36] Pro-business conservative commentators joined in opposition, writing that the Americans with Disabilities Act was "an expensive headache to millions" that would not necessarily improve the lives of people with disabilities.[37]

Once you have been hired and started work, your employer cannot require that you take a medical examination or ask questions about your disability unless they are related to your job and necessary for the conduct of your employer's business. Your employer may conduct voluntary medical examinations that are part of an employee health program, and may provide medical information required by State workers' compensation laws to the agencies that administer such laws.
